Application filed November 20, 1916. Serial No. 132,462.

T 0 all whom it may (-oncern:

Be it known that l, VVEs'roN M. FULTON, a citizen of the United States of America, and a resident of Knoxville, Tennessee, have invented a new and useful Improvement in Radiator-Casings, which invention is fully set forth in the following specification.

This invention relates to heat-regulating devices, and more particularly to radiator casings in which thermosensitive means, subject to room temperature, is used for automatically operating dampers for controlling the flow of heated air through the casing.

in my Reissue Patent No. 14:,309, dated June 5, 1917, I have disclosedv a radiator casing wherein the t-he-rmosensitive means is positioned within a downwardly directed conduit communicating adjacent its upper end with the room, and communicating adjacent its lower end with an upwardly directed passage in direct heat-interchanging relation with the end-section of the radiator, whereby, owing to the heating influence exerted by the radiator on the air in said passage, a circulation is maintained over the thermosensitive means. To secure the most efficient operation where the radiator end-section constitutes the separating means between the main radiator-receiving portion of the casing and said passage, this radiator sect-ion mustbe of the same size as the interior cross section of the casing. and constitute a partition closing communication between said passage and the portion of the casing inclosing the main radiator sections. This necessitates theemployment ot a special endsection in the form of a hollow plate or Wall conforming to the interior of the casing. lit is an object of this invention to provide a radiator casing, having an air-passage 1n heat-interchanging relation with the radiator whereby to induce a circulation of air over thermosensitive means mounted in a conduit communicating with said passage, which may be used with any radiator without respect to the type of endssection employed thereby.

Another object of this inventioniis to provide a device "of the type characterized wherein thereis an air passagein heat-interchanging relation with the radiator, hut

closed against communication with the in-' terior of the main radiator-receiving port on I of the casing, without necessitating a casing that closely fits the end section oi the radiator, whether a special end-section be employed or not. i

A further object of this invention is to provide a device of the type indicated that maybe inexpensively constructed in stock sizes and applied to any type of radiator, provision being made .for any lack of perpendicularity of the end-section of the radiator to the floor or" the room in which it is placed.

Further objects relate to the provision of radiator casings that are simple in construction, easy of installation and efficient inoperation.

Stated broadly, the invention comprises, in combination with a radiator, a casing therefor having dampers for controlling the flow ofi heated air therethrou'gh, therrnosensitive means operatively connected to said dampers for actuating the same, a conduit through which a circulation of air is induced and Within which current said thermosensitive means is positioned, said conduit being open to the room, preferably adjacent its upper end whereby it receives air at a level intermediate the upper and lower strata of air in the room with which it communicates, and an air-passagewith which said conduit communicates and which is in heat-interchanging relation with the radiator to induce a circulation of air over said thermosensitive means, one wall of said pas sage comprising a heat-conductingpartition in heat-interchanging relation with said radiator and, by preference, in contact there with. Said conduit and passage are shown as provided in an extension of the casing proper, and the conduit is insulated trom- ---sponding parts in the several figures,

F ig. t3 a face and end view of a heatconducting wall suitable for use with an end-section as shown in Fig. 5.

Referring in detail to said drawings, 1 represents plurality of radiator sections of any preferred type, and 2 a casing for inclosing the same. The upper portion of the radiator-inclosing portion of said casing is provided with damper-controlled openings for regulating the flow oi heated air through said casing. Tn the form shown (Fig. 2), the casing is provided with a hood 3. and openings -1- are provided in the wall separat ing the radiator-inclosing portion from said hood, said openings being controlled by dampers pivotally connected to an operating linlt ll.

Siaid casing E2 in the term shown is provided with an extension 7, the hood also preferably extending over the top of said extension. llithin this extension a vertical depending partition 8, which terminates just above the iloor 9 oi, said extension, divides the interior thereoi into two communicating compartments l0 and 11. The compartment 10, which constitutes a downwardly directed conduit, is provided with an inlet opening 12, preferably adjacent its upper end whereby it receives air at a level intermediate the upper and lower strata ol air in the room with which it commimicatcs. "While this compartment is herein designated a conduit, it is to be understood that the term is used as generic to any suitable inclosure through which air may be drawn to pass over a thermosensitive device in operative relation thereto. Compaitment 11, which constitutes an upwardly directed air passage, is provided with an exit opening 13 adjacent its upper end, shown as provided in the wall separating the extension 7 from the hood 3.

These compartments are in communication adjacent their lower ends, as by the opening 14 left between the end of partition 8 and the floor 9, said opening constituting an out let for conduit 10 and an inlet for passage 11.

To separate air-passage 11 from the radiator-containing portion of the casing, a wall 15 of heat-conducting material is mounted in heat-interchanging relation with the endsection of the radiator. This wall is preterably of such size and shape as to close communication between the interior of the main vportion ot' the casing and the passage, and,

neonate by preference, is supported in contact with the end-section of the radiator. or preferred form of radiator end-section may be used, two types being shown on the drawings. The preferred construction 3) comprises a generally rectangular, impert'orate, hollow plate or Wall 16, and when such an end-section is employed, wall 15 may be flanged or bent angularly along its side edges, as shown at 17, to conform with the shape of and to embrace the side edges of said section. This wall may be positioned in engagement with the end-section by slipping the same longitudinally over such sec tion. Tl desired, however, an end-section 16' of the more common type shown in Fig. 5 may be employed, in which event the heatconducting wall may be flanged or bent Any usual along its side edges, as shown at 17 in Fig. 4

6, to conform with the shape of and to embrace the side edges of said section, so that the same may he slipped into position longitudinally thereof. i ilthough not entirely necessary it wall 15 tits the interior crosssection of the casing 2, means are preferably provided for mounting or positioning said wall within said casing, said means also preferably providing for any lack ot' perpcndicularity of the end-section ot the radiator to the floor of the room. lo the form shown flanged members 18 are secured to the wall 15 adjacent its edges in any suitable way, as by riveting or spot welding, said flanged members preferably extending throughout the length of said wall. The flange of each of said members provides an inwardly directed locking edge. as shown at 19, to interlock with flanged members 20 suitably attached to the inner tacos ot' the walls'ot' the casing and preferably extending throughout the length or wall 15, said members 20 each providing a longitudinal groove and terminating in an outwardly directed locking edge as shown at 21. These interlocking members constitute a slip-contherebetween.

Positioned in the current of air flowing through said conduit is any suitable thermoscnsitive device the same being preteralbly mounted in said conduit and shown as concealed therein. Said thermosensitive device is provided with an operating stem 23 which extends through the partition 8 and is pivotally connected to a lever 2ioperatively connected to the damper-operating linlr 6.

To protect the conduit 10 and thern'iosensitive device from the heating influence oi the radiator, wall 15 and passage 11, partition 8 is made non-heat-conducting in any simi lar way, as by ci'mslructing the same of sheet metal lined with corkor other heat-insulating material; floor 9 is also preferably made non heat-conducting in a similar way; the

ion

Bill) top of said conduit is covered with heatinsulating material, as shown at 25; and the walls of the conduit are insulated from the walls of the casing proper, so as to prevent conduction of heat therebetween, as by Hanging the walls of said casing and the extension 7, as shown at '26, and interposing any suitable heat-insulating material 27.

In operation, the end radiator-section l6 heats the partition 15 which in turn heats the air in the upwardly directed passage 11. This air rises and passes freely into the room through the outlet opening 13. Air is drawn in through inlet 12 of conduit 9 and, passing over thermosensitive device 22, enters the passage 11. T he. thermosensitive device, subjected in the form shown to air from a level whereby it represents average room-temperature, responds to the temperature thereof and operates the dampers 5 through the intermediate connections, controlling the flow of heated air through the main portion of the casing 2. The heat-insulating partition 8 protects the thermosensitive device from the direct radiation of the heat-comlucting wall 15; the heatinsulating floor 9 protects said device from convection currents rising from the lower portion of the radiator: the insulating wall 25 protects said device from the heating influence of the air in the hood; and the insulating strips 2? protect said device from heat conducted along the walls of the casing to the extension.

By the provision of a heat-condruting wall of the type illustrated at 1:"), it will be perceived that,the air-passage 11 is separated from the main radiator-containing portion of the casing irrespective of the type of radiator end-section employed and any lack of conformity between the cross-sections of the radiator and -asing. and the thermosensitive device is subjected to air at room-temperature by a circulation maintained independently of the air in the radiator-inclosingportion of the casing. said wall with bent portions, as shown at 17, the, same may be readily slipped into position longitudinally of the radiator-section, and by the use of the interlocking mom.- bers 18 and .20 a slip-connection is provided between. said wall and the walls of the casing, which enables assemblage by engaging the locking edges 19 in the grooves provided by the members 20 and sliding the smile longitudinally therein, and which permits said wall to engage the radiator section closely although assuming a position out of perpendicular to the floor of the room.

While the illustrated embodiment has been described with considerable particularity, it is to be expressly understood that the invention is-not to be restricted to the construction shown upon the drawing, for it is capable of receiving variety of mechanical By providing expressions, some of. which will readily suggest themselvesto those skilled in the art, while certain features thereof are capable of use without other features thereof.
